Note :
1. It is very important that the liquid gaskets listed above or their exact equivalent be used on the vehicle.
2. Be careful to use the specified amount of liquid gasket. Follow the manufacture's instructions at all times.
3. Be absolutely sure to remove all lubricants and moisture from the connecting surfaces before applying the liquid gasket.
The connecting surfaces must be perfectly dry.
4. LOCTITE 515 and LOCTITE 518 harden upon contact with a metal surface.
Do not apply LOCTITE 515 or LOCTITE 518 between two metal surfaces having a clearance of greater than 0.25 mm (0.01 in). Poor adhesion will result.

Inspection and Repair
Make all necessary adjustments, repairs, and part replacements if wear, damage, or other problems are discovered
during inspection.


• Ring gear, pinion gear
• Bearing
• Side gear, pinion gear, cross pin
• Differential cage, carrier
• Thrust washer
• Oil seal


Visual Check
Inspect the following parts for wear, damage, or other
abnormal conditions.



Ring Gear Replacement
(1) The ring gear should always be replaced with the drive pinion as a set.
(2) W hen installing the ring gear, apply LOCTITE 271 o

4 Gage plate : 5-8840-2087-0




(3) Set the dial indicator to “0”. Place it on the mounting post of
the gaging arbor with the contact button touching the
indicator pad. Force the dial indicator downward until the
needle has made a half turn clockwise. Tighten down the
dial indicator in this position.




(4) Position the plunger on the gage plate. Move the gaging
arbor slowly back and forth and locate the position at which
the dial indicator shows the greatest deflection. At this
point, once again set the dial indicator to “0”.
